RE-E NFORC ING PLATE FOR SAW-HANDLES.

SPECIFICATION formingpart of Letters Patent No. 280,612, dated July 3,1883.

Application filed April 28, 1883.

To all whom it may concern: 7

Be it known that we, WILLIAM H. HANKIN, J r., and OoRNELIUs TINNEY, bothcitizens of the United States, residing at Brooklyn, E. D., in thecounty of Kings and State of New York, have invented new and usefulImprovements in Re-enforcing Plates for Saw-Handles, of which thefollowing is a specification.

This invention relates to a re-enforcing plate adapted more especiallyfor haudsaws; and it consists in the combination, with a saw-blade andahandle, of a re-enforcing plate provided with a groove adapted for thereception of the blade, as hereinafter more fully set forth. Theconstruction of the plate is hereinafter more fully described.

This invention is illustrated in the accompanying drawings, in whichFigure 1 is a side view of part of a saw containing the improve ment.Fig. 2 is an inverted plan view of the re-enforcing plate. Fig. 3 is aplan view of said plate. Fig. 4 is a section in the plane 00 00, Fig. 2.Fig. 5 is a section in the plane y Fig. 3.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a part of a saw-blade, and B isthe handle, the wings of which have slots or holes through which andthrough corresponding slots or holes in the saw-blade are passed boltsor screws 0, by which means the bladeand handleare connected. The tail Iof the blade A extends under the bridgeH of the handle. A difficultyheretofore experienced has been the liability of the bridge H to breakby the strain put upon it in the operation of the saw. To avoid, thisdifficulty we'provide a re-enforcing plate, D, which extends along thebridge H. A convenient way of attaching the plate D is by a screw, G, asshown in Fig. 1.

Figs. 2 to 4, both inclusive, show in detail the construction of there-enforcing plate D. The same consists of a head, K, which can beadapted for the accommodation of the screw G, Fig. 1, or other fasteningdevice for attaching the plate to the handle. From the head (No model.)

K extend wings or arms 6 6, connected at or near their outer ends by abridge, f. This bridge f is so arranged as not to break the i the. sametime is light and easy to handle.

Of course we may modify the construction of the plate D by extending thebridgef along the entire upper face of the plate and making said bridgef continuous with the head K; but the construction shown in the drawingsfurnishes a sufficiently strong device, and as the least amount of metalis used the device is lighter and cheaper. As shown in Fig. 3, the topof the bridge f is flush with the top of the wings of the plate D, sothat the top of the device offers an even surface, while the under sideof the bridge f lies above the lower surface of the wings e 6, so thatthe space between said wings which is adapted for the insertion of thetail I of the blade A is not broken.

What we claim as new, and desire to secure by Letters Patent, is-

1. The combination,with a saw-blade and a handle, of a ire-enforcingplate provided with a groove to receive the tail of the blade andapplied to the bridge of the handle, substantially as described.

2. A re-enforcing plate for saw-handles,consisting of a head, K, arms orwings e e, an in termediate groove, and a bridge, f, substantially asdescribed.

In testimony whereof we have hereunto set our hands and seals in thepresence of two subscribing witnesses.
